The present invention refers to an optimized structure of a control surface (9) for aircrafts, such as elevators, rudders, landing flaps, ailerons, and other similar lifting surfaces. The control surface (9) comprises a front spar (1), a rear spar (2), a plurality of ribs (10-14) and at least one hinge fitting (7,14) and an actuator fitting (8,8') joined with the front spar (1). At least one rib (10-14) is connected with the actuator fitting and it is arranged so as to define an oblique angle (±, ²) with the front spar (1). One or more ribs are located in correspondence with the main torsion and bending load paths created in the control surface during flight, landing or takeoff, so the same structural behavior of the control surface is achieved, but, with a reduced number of ribs, so that the weight of the control surface is reduced.
